Thesis (MScFor (Forest and Wood Science))--University of Stellenbosch, 2009. / In this study, a multi-stem harvesting operation was observed and time studies carried out on
its machines. A stump-to-mill simulation model (System 1) of this system was subsequently
built using a commercial simulation software package (Arena 9) and data from the time
studies were incorporated into the model. Following this, another two stump-to-mill multistem
models (Systems 2 and 3) were built using the same simulation software package and
parameterised input data. These two models represented hypothetical systems which were
tested against System 1 and against one another in terms of machine balance within the
system, production rate and cost. System 2 used identical equipment to System 1, but
practised alternative operating methods. Some of System 3’s machines and operating
methods differed from those in Systems 1 and 2.
The objectives of the study were to:
1. Determine whether or not commercial simulation software can be used to adequately
model forest harvesting operations.
2. Gauge potential system balance, production and/or cost improvement/s achievable
through application of simulation-based operation adjustments.
3. Define beneficial equipment operation and application practises for multi-stem systems.
4. Through construction and use of the commercial software package in producing forest
harvesting operation models, evaluate the software’s usability in terms of its
applicability to and ease of use in such models, as well as its ability to meet forestrybased
user requirements.
